  1. Installing with my file DSDT, do not need some kexts. Note : you need FakeSMC.kext (it’s necessary kext for each Hackintoshes)

    OK works, included patches in DSDT :

    – sleep (u dont need SleepEnabler.kext or other kext)
    – restart – reboot (u dont need EvOreboot.kext or other kext )
    – fix issue reset cmos – bios (u dont need ElliottForceLegacyRTC.kext or other kext)
    – Shutdown (u dont need kext for shutdown )
    – AppleIntelCPUManagemet – enable (u dont need NullCpupowermanagement.kext or other disabler)
    – and more fixs

    and you dont need Disabler.kext

    NOT add to DSDT patches :

    – audio this built in this mobo (audio work with patched AppleHDA.kext or VoodooHDA.kext)
    – graphics card (work with other kexts – injector or EFI String or GraphicsEnabler … )

    Copy this file dsdt.aml to folder /Extra on partition disk with Snow Leopard.

    I’m testing this DSDT on 10.6.6

    I’m add kexts use :

    – LAN – RealtekRTL81xx.kext ( RealtekRTL81xx-0_0_67.pkg )
    – AUDIO for ALC 888 , kexts : add ALC8xxHDA.kext , add HDAEnabler.kext , patched AppleHDA.kext

    Also DSDT for this mobo GA EP41-UD3L included is in program “DSDT Auto-Patcher”

  2. I have the same motherboard rev.3.3 with latest bios, ur procedure doesnt work for me.
    I’m stuck in the beginning of the OSX installation, after language selected it simply says “cannot install mac os x on this computer”.

    any ideas?


    1. If you set up your bios the same way i do, problem should be in some other component of your comp. .
      your HD? (use SATA, not PATA)
      your CPU? (it should be core2duo or quad, not pentium D or older)
      your graphic card?
      do you have USB keyboard and USB mouse?

      and so on…

  3. hello
    My mytherboards GA-EP41-UD3L
    The problem that i have is that when i complete the installation everything works properly except the fact that my pc don’t restart or turn into sleep mode. What can i do to fix it??
    What is DSDT that how can i install it??

    Can you make a video tuturial about all these please thanks a lot waiting for you reply..

    1. Check out the BIOS settibgs, did u set acpi suspend type to s3?
      what installation method did u use?

    2. to fix restart u can try copy EvOreboot.kext from GA EP41-UD3l extra pack (download link is at top) to your Extra directory, and use kext utility to repair permissions…
      note: sleep will not work without dsdt but u can use it without sleep

  4. Hi guys,

    same MoBo, Pirate works, SL says after many lines of text: Still waiting for root device….
    any ideas?

    Thanks a lot

    1. Hi jojo,
      do u have SATA HDD and DVD?
      be sure that HDD is sata 1 and DVD sata2, disconnect any other sata device
      in bios set “on chip sata mode” to non combined, “pata ide set to” disabled …
      i think that should fix your problem …
